In the directive 2004/107/EC (Fourth Daughter Directive), the EU has set a target value for polycyclic aromatic hydrocarbons (PAH) for the protection of human health; the target is defined in terms of concentration of benzo(a)pyrene (BaP) which is used as a marker substance for PAHs generally: the BaP annual mean value may not exceed 1 nanogram per cubic metre (ng/m3). The target value enters into force 31.12.2012.

This report presents an overview and analysis of
air quality in Europe from 2002 to 2011. It reviews progress
towards meeting the requirements of the air quality
directives and gives an
overview of policies and measures introduced
at European level to improve air quality and
minimise impacts. An overview of the latest findings and
estimates of the effects of air pollution on health
and its impacts on ecosystems is also given.

The graph shows the percentage frequency distribution of stations (on the y-axis) in the EU Member States versus the various concentration classes (on the x-axis, in ng/m3). The vertical line corresponds to the target value set by the EU legislation.
